Fasteners for fur clothing are intended to enable a detachable and ifpossible invisible connection between the two parts of a clothing. Theconnection must safely hold but in so doing is not allowed to impair thefit of the furcoat or, in the case of clothing not made of fur, to causeunfashionable formation of folds. For this purpose, fasteners have beenprovided which consist essentially of a baseplate to be fastened at theone clothing part, comprising a spring lever and a pin, and a loop to befastened at the other clothing part. One arm of the spring levercooperates with the pin and the other arm spring mounted on that side ofthe baseplate facing away from the pin. The lugs of the spring leverdetermining the pivot axis thereof, are supported in bearing shells ofthe baseplate open towards the leaf spring. A snap function is providedby the cooperation of the leaf spring and the short lever arm and thespring lever is always resiliently forced into one of its end positions.In order to connect the clothing parts, the loop is pushed over the longarm of the spring lever and is thereupon secured by the longer lever armsupported on the pin and subjected to the spring action, said pin beingin engagement with a recess formed in the lever.

Fasteners are known which comprise a curved L-shaped upper member and apin, said member, however, being rigidly connected with the baseplate.The loop must be forced through a gap between said member and the pinagainst the force of a leaf spring. In this case the baseplate isarranged on the fur in such manner that the L-shaped member extendsparallel to the fur edge and not vertically thereto as is the case withfasteners with a turnup lever. These fasteners, however, did not proveto be practical, because it is very troublesome to thread the loop overthe L-shaped member, because the latter is hidden in the dense fur.Additionally, a leaf spring supported on the pin will never be able toclose the gap as tightly as is the case, for instance, with a pin whichin the closed position snaps into a recess. If, to increase the closingpower, a very strong leaf spring is used, the tender fur material may bedamaged due to the considerable tensional forces to be applied.

It is an object of the invention to provide a fastener with improvedsnapping function in comparison with the simple snapping function of thespring, and to increase the closing power thereof. It is another objectof the invention to secure the bearing lugs of the lever against jumpingout of the bearing at the narrow side of the baseplate in case ofunskilled displacement of the lever. Another object of the invention isto provide a fastener with a leaf spring arranged on the one side of thebaseplate, the spring being mounted in such a manner that it will remainfixed against rotation in case its rivet joint should loosen so that thespring always cooperates with the shorter lever arm. In thisarrangement, the spring is to have a only small projection with respectto the baseplate on the side facing away from the lever.

SUMMARY OF THE INVENTION In accordance with the invention, the recess inthe longer lever arm adapted to come into engagement with the pin, isarranged slightly eccentrically with respect to the axis of the pin, sothat a special pressure is required to cause the pin to snap into therecess. In order to guide the head of the pin safely towards thepan-shaped recess, the lever is still provided with a groove extendingfrom the edge of the recess and tapering towards the end of the longerlever arm. When the lever arm and the pin contact each other, therounded head of the pin first engages within the grooves and then withincreasing pressure slides towards the recess, finally enteringthereinto in snapping engagement.

The leaf spring by its snapping function determines both and positionsolthc preferably L-shaped longer lever arm and with a leaf contributesin keeping the fastener shut. The main portion of the closing force,however, is provided by the snapped-in pin, which is allowed by theelastic properties of pin and lever material. The forces required forthe closing and opening are substantially greater than with a closingforce exerted by a spring-loaded lever alone, and an inadvertant openingis rather impossible.

In order to prevent a possible rotary movement of the leaf spring aboutthe rivet joint, i.e., about the pin, the spring is inlaid in adepression formed in the baseplate. The thickness of the assembly isreduced in this way and the fastener may be sewed in easier.

The bearing lugs of the spring lever are prevented from jumping outofthe bearing shells in that extensions provided at the narrow side ofthe baseplate, are rolled about these lugs to form closed hinge sleeves.

FIG. 5 is a sectional view on a reduced scale of a fastener employedwith a fur material.

DESCRIPTION OF THE PREFERRED EMBODIMENT The fastener 1 comprises asubstantially rectangular baseplate 2 having its corners rounded at theone short side thereof. The other short side is slightly shortened andprovided with two extensions rolled in to form closed hinge sleeves 3aand 3b (FIG. 1) in such a manner that the pivot axis of the hinge liesin the plane of the baseplate 2. A spring lever 4 is supported in thespaced hinge sleeves by means of two lateral lugs 50 and 5b formedintegrally with the spring lever 4. The spring lever 4 is a two-armedlever with a shorter lever arm 6 and a longer lever arm 7 which issubstantially formed like an L.

The baseplate 2 is provided with a groove 8 on the underside whichgroove appears as a projection on the upper side. A leaf spring 9 isarranged in this groove extending beyond the hinge axis, the depth ofthe groove being selected in accordance with the thickness of the spring(FIG. 2). Bores 10 and 11 (FIG. 3) are provided in the spring 9 and thebaseplate 2 near the end facing away from the hinge 3. The thinnerportion of a cylindrical pin 12 is inserted in the bores from the upperside and riveted on the baseplate 2 to fasten pin and spring after awasher 13 has been placed on (FIG. 3).

The spring 9 presses itself against the shorter lever arm 6 between thehinge sleeves 3a and 3b, with the spring force acting in directiontowards the axis of rotation of the two-armed lever 4. Two positions ofthe lever are characterized with respect to the baseplate by thecooperation of the lever arm 6 and the spring 9. In the one position,the lever 4 has been pivoted about the axis of rotation against theforce of the spring in such a manner that the long lever arm 7 ispivoted away from the baseplate 2. In the other position, the lever arm7 lies on the pin 12. During the lever movement from the one positioninto the other, the spring is bent off at maximum.

The spring lever 4 is provided with a panlike recess 14 in its long arm7. The circular recess has approximately the same diameter as the pin 12provided on the projection on the baseplate. The recess 14 is slightlyeccentrically offset towards the hinge 3 as compared with the pin 12, sothat in the abovedescribed contact position between lever arm 7 and pin12 the recess 14 is not arranged exactly above the upper end of the pin12. The lever arm 7 is furthermore provided with a groove 15 with itsdeepest and broadest point being arranged at the edge ofthe recess 14and which groove tapers towards the end of the lever arm 7 (FIG. 4), thedepth of the recess 14 being greater than the maximum depth of thegroove 15. Because of the eccentric arrangement of the recess and thepin, the latter has part of its rounded end face 12a engaging with thegroove 15. When closing by the exertion of pressure on the lever arm 7,the pin is guided in the groove by its upper portion towards the recesscenter point until it slips into the deeper recess 14- for snappingengagement therein, with an elastic deformation occurring. Then the pin12 presses itself tightly against that part of the inner face 14a of thecircular recess 14 averted from the hinge (FIG. 3).

The baseplate 2 is provided with some bores 16 along the flange aroundsaid groove 8 in order to sew the fastener to the one part of thegarment, for instance a fur. The parts of the fastener remaining visiblemay be covered with a type of leather matching with the fur, the leatherbeing pasted by means of an adhesive in a groove 17 provided on theupper surface ofthe lever arm. The bottom of the groove 17 may beprovided with impressions (not shown). To close the coat when thefastener l is open, i.e., when the spring lever 4 is swung off from thepin 12, a loop 18, which is fastened at the other part of the coat, ispushed over the long arm 7 of the spring lever 4. Then the lever 4 isswung back while overcoming the spring force, and the pin 12 comes intoengagement with the recess 14 while overcoming the elastic deformingforce as described.

The fastener is arranged vertically with respect to the edge of the furso that the loop 18 with closed fastener will draw at the short leg ofthe L-shaped spring lever 4 directly adjacent to the pivot axis of thehinge 3. Even with stronger forces acting on the loop or the ring (forinstance a person leaving a car when the coat will frequently slide) thefastener remains closed, because the tensional forces near to the hingeare acting at a very short lever arm and therefore are not great enoughto open the interlocking engagement ofthe long lever arm with thecylindrical pin.

The spring 9 is made of spring steel, and the other parts of thefastener may be made ofiron, brass, light metal or plastics; theplastics may in particular by a synthetic resin.
